THE HAGUE, Netherlands — Israel’s preliminary analysis of the damage caused by U.S. strikes on Iran’s main nuclear facilities — based in part from on-the-ground assessments — shows the attacks inflicted widespread destruction, a senior Israeli official said.

The official, granted anonymity to speak candidly, said that Tehran has been “actively trying to hide the damage” from the attacks, which President Donald Trump said in The Hague on Wednesday had all but eliminated Iran’s enrichment program.

Trump, who repeatedly defended the effectiveness of the strikes at the NATO Summit, made reference to individuals who had been on the ground to assess the damage, without providing details.

“I can’t say it’s a final assessment, because we’re less than a week after. It’s not like we can send officers openly. But that’s the indication we have now,” the official said.

A spokesperson for Iran’s foreign ministry on Wednesday said the bombing raid “badly damaged” the nuclear sites, but the Iranian government has said it will continue its nuclear efforts, which it insists are for peaceful purposes.

A full review of the mission could take weeks, and experts have expressed skepticism of declarative statements by Trump and Defense Secretary Pete Hegseth that the U.S. operation was a success within mere days of the attack.

“Battlefield damage assessment is an imprecise art, with initial estimates frequently being way off,” said Patrick Clawson, an expert on Iran and director for research at The Washington Institute for Near East Policy. “I would be very suspicious of any claims — by Iran, by Trump, by Israel — about what has happened to Iran’s enriched uranium stocks or to its centrifuges.”

Israel’s preliminary findings come after an initial assessment from the U.S. Defense Intelligence Agency cast doubt on the effectiveness of the American strikes, stating with low confidence that Iran had retained the core elements of its nuclear program despite the attacks, one U.S. official familiar with the findings told The Times. The DIA assessment was first reported by CNN.

The U.S. attack followed nine days of an Israeli military campaign that decimated Iran’s air defenses, its military leadership and its ballistic missile stockpiles, while degrading its nuclear facilities.

Israeli intelligence has also monitored the reaction to the campaign among Iranian leadership, which has struggled to comprehend the extent of the damage itself, the Israeli official said.

“We don’t believe everyone in the leadership knows what really happened, because the whole program was compartmentalized — they weren’t sharing a lot of information, and a lot of the officers who were highly involved on the ground level were eliminated,” the official continued. “So a lot of the top leadership hasn’t fully begun to understand what’s happened.”

The developing intelligence picture comes as Trump defended the U.S. mission, called Operation Midnight Hammer, during multiple appearances at the NATO Summit in The Hague on Wednesday.

“It’s been obliterated, totally obliterated,” he said of Iran’s nuclear facilities. Addressing the DIA report, he added, “They did a report, but it was like, if you look at the dates, it’s just a few days after.”

The U.S. deployment of massive, “bunker-buster” munitions targeting Iran’s main nuclear sites — including six dropped on Fordo, a facility burrowed deep into the side of a mountain — was intended to bury its most advanced equipment and most highly enriched uranium, which can be used to build nuclear warheads.

Initial assessments of the damage were unclear, but since then, Trump said, “we’ve collected additional intelligence.
We’ve also spoken to people that have seen the site, and the site is obliterated.”
